Upgrade the Atmel ATMega128 CPU to the newer ATMega2561 for added features and operatability. Base price is for the programmed CPU only. If you are not comfortable working with surface mount devices, you can send us just the board, we will change it out for you and pay for the return shipping (select Installed & Tested above for this option).

NOTE: DO NOT ORDER WITH A NEW CONTROLLER AS THEY ALREADY COME WITH THE NEW CPU
